Three 9 m × m AG mills are used in parallel in a dry operation to grind a feed nominally passing 32 cm, which is the product of a gyratory SAG mills is driven by a 4023 hp motor and runs at a constant (12 rpm rotational) speed (, 85% of critical speed) in one direction.
WhatsApp: +86 18838072829SAG mills use a combination of steel balls and rock particles as grinding media, while AG mills use only the ore itself. Both types of mills are used for grinding ore in mineral processing operations, but SAG mills are larger in size and can grind larger quantities of ore. AG mills, on the other hand, are smaller and are typically used for ...

WhatsApp: +86 18838072829Semiautogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diametertolength ratio of around two. With this high aspect ratio, SAG mills generate both thrown and cascading ballmilling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter. These

The contract includes the design and manufacture of a Ø 40' x 29' SAG mill. The mill will be driven by a Gearless Motor Drive (GMD) which at MW is equal to the largest grinding mill power ever used in the mining industry.

WhatsApp: +86 18838072829Rod mills are limited in size to 2000 kW because the longest commercial grinding rod available is 6 m long. For this reason rod mills are rarely selected in the present day environment of large AG/SAG mills and large ball mills. However, it is necessary to discuss their operation because a Rod mill product has a similar slope to AG/SAG mills.

Once the basic operating conditions have been defined for the mill designer then, and only then, can he begin taking into account shell and head stresses and trunnion bearing sizes required to carry the load and to give the required openings for feeding and discharging the mills. Mill heads are key structural components of ...
WhatsApp: +86 18838072829We have an application in a SAG Mill where we have installed an electronic ear in order to listen the noise produced by the balls falling to the bottom of the mill. Our idea is to convert the amplitude and frequency of noise to a 420mA signal (or something else) in order to determine if the ball is crushing the mineral or the mill lining.
